SDELC100 Limestone Multi-Parameter Analyzer
The SDELC100 Limestone Multi-Parameter Analyzer is an automated thermogravimetric analysis system designed for the rapid determination of multiple quality parameters in limestone. By continuously monitoring sample mass changes under controlled temperature and atmosphere conditions, the instrument generates time–temperature–mass curves and automatically calculates moisture, calcium oxide (CaO), magnesium oxide (MgO), and loss on ignition (LOI).
The analyzer accommodates up to 12 samples and automatically performs sample loading, weighing, analysis, and unloading. Its dual-furnace configuration enables alternating operation for higher throughput, while samples can be added or replaced during an ongoing test. In addition to limestone analysis, the system can also be used for rapid determination of moisture, ash, and volatile matter in coal.
Key Features
Multi-Parameter Analysis in One Instrument
Determines multiple limestone quality parameters, including:
- Moisture
- Calcium oxide, CaO
- Magnesium oxide, MgO
- Loss on ignition, LOI
The analyzer can also perform rapid moisture, ash, and volatile matter analysis for coal samples.
High Level of Automation
After up to 12 prepared samples are loaded, the instrument automatically completes:
- Sample transfer
- Weighing
- Heating and analysis
- Result calculation
- Sample unloading
The entire analytical process can run unattended.
Dual-Furnace Design for Higher Throughput
Two furnaces operate alternately to reduce waiting time and improve laboratory efficiency. Samples may also be added or replaced while the instrument is operating, supporting more flexible sample workflows.
Reagent-Free and Easy to Operate
The analytical process requires no chemical reagents and generally requires minimal sample preparation. Once the powdered sample has been weighed, the operator can start the test with a single command, reducing operating complexity and routine analysis costs.
More Application-Relevant CaO Determination
The instrument determines CaO based on the release of CO₂ during CaCO₃ decomposition. This approach reduces interference from calcium present in other chemical forms and provides results that are more directly relevant to limestone desulfurization performance than conventional titration or X-ray fluorescence methods.
Accurate and Traceable Results
Real-time recording of sample mass, furnace temperature, atmosphere, and test duration provides a complete analytical curve and improves the traceability of test results.
